AI Technical Summary

Benefits of technology

The solution effectively improves network performance by ensuring that signals from WBTs meet the necessary delay and jitter criteria, maintaining reliable communication and reducing the adverse effects of packet-switched network variability on MTSO operations.

Problems solved by technology

With the growth of packet-switched (vs. circuit-switched) multi-hop backhaul, and the variability in packet delivery times, differential delay can become a significant problem for legacy MTSOs receiving WBT signals over packet-switched networks.

first embodiment

[0011]In the present disclosure, a network management system (NMS) that manages operations of a communication system including a mobile telephone switching office (MTSO) coupled to a plurality of wireless base terminals (WBTs) by way of a corresponding plurality of network elements, can have a network configuration element that identifies for each of the plurality of WBTs a resultant communication path to the MTSO according to a plurality of performance characteristics calculated from alternative communication paths connecting combinations of the WBTs to the MTSO.

second embodiment

[0012]In the present disclosure, a computer-readable storage medium operating in a network management system (NMS) that manages a communication system including a mobile telephone switching office (MTSO) coupled to a plurality of wireless base terminals (WBTs) by way of a corresponding plurality of network elements, can have computer instructions for identifying for each of the plurality of WBTs a resultant communication path to the MTSO determined from a plurality of communication path alternatives between the WBTs and the MTSO that satisfy a desired differential delay threshold.

third embodiment

[0013]In the present disclosure, a network element that transports messages between a wireless base station (WBT) and a mobile telephone switching office (MTSO), can have an operating element that receives from a network management system (NMS) provisioning information comprising a resultant communication path between the network element and the MTSO determined by the NMS from a plurality of communication path alternatives between the WBTs and the MTSO that satisfy a desired differential delay threshold.

[0014]FIG. 1 depicts an exemplary embodiment of a communication system 100. The communication system 100 can comprise a plurality of wireless base terminals (WBTs) 101, also commonly referred to as base stations, distributed throughout a network under a frequency-reuse methodology to provide wireless services to roaming end users 108 over a large geographic region (such as a city, state or nation). The end users can use any wireless device capable of communicating with the WBTs 101 i...

Abstract

A method and apparatus is disclosed for improving network performance in a communication system. A system that incorporates teachings of the present disclosure may include, for example, a network management system (NMS) that manages operations of a communication system including a mobile telephone switching office (MTSO) coupled to a plurality of wireless base terminals (WBTs) by way of a corresponding plurality of network elements, having a network configuration element that identifies for each of the plurality of WBTs a resultant communication path to the MTSO according to a plurality of performance characteristics calculated from alternative communication paths connecting combinations of the WBTs to the MTSO. Additional embodiments are disclosed.

Description

RELATED APPLICATION[0001]U.S. patent application Ser. No. 11 / 427,142, filed Jun. 28, 2006, by Small et al., entitled “Method and Apparatus for Maintaining Network Performance in a Communication System,” now Patent Application Publication No. US 2008 / 0003974 A1, published Jan. 3, 2008, incorporated herein by reference in its entirety.FIELD OF THE DISCLOSURE[0002]The present disclosure relates generally to communication systems, and more specifically to a method and apparatus for improving network performance in a communication system.BACKGROUND[0003]In a cellular system, wireless base terminals (WBTs) cover a wide geographic area utilizing frequency-reuse techniques. It is not uncommon for WBTs to have overlapping coverage areas to avoid null or dead spots that can cause dropped calls. In overlapping coverage areas it is possible for a mobile phone to submit a mobile origination call to a mobile telephone switching office (MTSO) by way of two or more WBTs.[0004]In order for the MTSO ...
